ff df- Maw , ATTORNEY Patented Sept. 28, 1937 UNITED STATES PATENTOFFICE 1 Claim.

This invention relates to scraping devices for footwear and has for itsobject a simple inexpensive device by which lforeign material such aslmud and other objectionable substances adhering to footwear can beremoved therefrom with the utmost ease and dispatch to the end that thefootwear of a person about to enter a house, automobile, or the like canbe thoroughly cleaned of such foreign material and thus prevent soilingthe floor, rugs, or floor coverings as well as eliminating unsanitaryconditions, especially in rural districts, 'resulting from carryingforeign material accumulated on the footwear,y from the stables orpastures, into the dwelling.

It is a well known fact that there are a great many forms of scrapingdevices for this purpose, but it is the object of this invention toconstruct a device in which the scraper blade may be actuated by meansof levers and springs so that when the scraper blade use is not requiredit may be retracted from obstruction, and by the use of a simplemechanism be brought into position for use. Because of this actuatingmeans it is self cleaning.

The special construction and arrangement of the parts of this inventionare illustrated in the accompanying drawing of which; Fig. l is av frontplan view of the device showing scraper plate retracted. Fig. 2 taken online 2-'2 of Fig. l is a sectional side elevation showing thearrangement of the parts. Fig. 3 is a top plan view of the deviceshowing the blade retracted. Fig. 4 illustrates a sectional sideelevation of the scraper plate and the tension spring. Fig. 5 shows asectional side elevation of the scraper plate retaining member with thescraper plate removed, taken on line 5-5 of Fig. 3.

Throughout the drawing and description the same number is used to referto the same part.

Considering the drawing, this invention consists of an angular piece ofsheet steel I of reasonable strength, which is secured to a step orother convenient location and extended downward and at right anglethereto. On this downward portion are four overlapping members 3 asshown. In the channel of these overlapping members is movably secured ascraper plate. 2, which is retained in a vertical position by theoverlapping members 3 of plate I. Secured to plate I and extendingvertically and at right angles thereto is a fulcrum piece 4 in which thescraper plate actuating means 5 pivots. The inner end of actuating lever5 is pivotly secured to the scraper plate 2 by means of a bolt Ii. Bolt6 moves vertically in an elongated slot 'I which forms a limit movementslot. In plate 2 is a horizontal slot 8 which engages protrusion 9 ofplate I so that when the scraper plate is raised it will form a lockingmeans as shown in Fig. 2. In plate I are two horizontal holes I0 throughwhich screws or bolts may pass, that provide means for securing thescraper device to the step or other location. In scraper plate 2 are twoholes I 0A which form a means through which a screw driver can beinserted to contact screws in holes I0 in order to tighten the same intoplace when scraper plate is partly raised. The angular metal piece I isalso provided with the screw holes II, as shown in Figs. 3 and 5. Aftersaid screws have been tightened into place scraper rplate 2 is now freeto be raised or lowered. The rearward extending portion of member Icarries holes II providing another means for securing plate I to itslocation as shown in Fig. 3. The scraper plate 2 is frictionally heldagainst plate I by means of a spring I2, a friction washer I3, aretaining washer I4 and a nut I5 on bolt 6 as clearly set forth in Fig.4.

In the operation of this invention, the scraper plate 2 is raised sothat protrusion 9 slips into slot 8, thus holding scraper plate securedin a raised position ready for use, by a downward pressure of the footupon lever 5, as shown by the broken lines in Fig. 1.

To retract the scraper plate 2, an outward and downward pressure isapplied'to the top of the scraper plate which disengages protrusion 9from slot 8 and allows plate 2 to be readily collapsed into its originalposition on plate I.

Having now described this invention, I claim:-

A shoe scraper comprising in combination, a supporting plate, a scraperplate located next to and upon one side of the supporting plate, saidsupporting plate being provided with guiding devices wherein saidscraper plate may be moved upward and downward, the said guiding devicesbeing constructed to permit a limited movement of said scraper platetowards and from the supporting plate, a lever, a pivot pin attached tosaid lever and scraper plate, a coil spring borne by said pin andarranged against said supporting plate whereby said lever and scrapingplate are yieldingly connected, said supporting plate having a slot forthe passage and movements of said pin, said supporting plate beingprovided with a fulcrum piece, said piece being constructed and arrangedto engage the lever and afford a fulcrum therefor, said lever extendingbeyond the supporting plate and being operable by foot pressure, saidsupporting plate having a transverse protrusion, and said scraper platebeing constructed with a transverse opening and being movable by saidcoil spring into detachable engagement with the said protrusion to holdsaid scraper plate in raised position.
